LAMP-SOCKET.

Specification of Letters Patent.

Patented Aug. 5, 1919.

To all whom itmag concern:

Be it known that I, RALPH R. R001, a citizen of the United States, residing at the city of Cleveland, in the county of Cuyahoga and State of Ohio, have invented a new and use ful Improvement in Lamp-Sockets, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying thatprinciple, so as to distinguish it from other inventions.

This invention pertains to a lamp socket and more particularly to an appliance for firmly supporting the base of one or more incandescent lamps while being stored or transported preparatory to eventual use in electrical connection. The object of my invention is to provide a firm seat for friable lamps of this character which will be feasible and economical of manufacture, which will enable a lamp to be easily inserted and as readily withdrawn but to be incapable of dislodgment other than by manipulation. My idea furthermore comprehends an arrangement of a series of sockets in a suitable box which, according to the exemplification selected, is composed of sheet metal and suited to becoming a part of the regular equipment of an automobile.

With the foregoing and other objects in view the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the S00 e ofthe claims hereunto appended.

dverting to the drawing:

Figure I is a perspective view of a box formed with lamp sockets embodying my invention. I

Fig. II is a perspective view of a part thereof. p p

Figs. III and IV are enlarged top and. bottom plan views respectively of the socket itself. I

Figs. V and VI are enlarged relatively transverse and vertical sections respectively of the socket proper.

V Fig. VII is a section taken at an angle of 45 to the other sections.

Fig. VIII is a section of one socket with a 1 lamp in place.

The box may be of any size and shape de pending upon' the number of sockets which it shall be intended to accommodate and includes a compartment 1 and a top 2 hinged together at 3 and provided with a suitable lock connection at 4:. Carried interiorly in any approved manner above the bottom 5, so as to be held in place with respect thereto, is a structure embracing the principles of my mvention.

Such structure comprises, preferably but not necessarily, a pair of resilient plates 6 and 7 respectively, the latter of which overlies the former and is secured thereto by spot welding, riveting or otherwise, but only at definitely located points.

In the present instance the box is to be supplied with five sockets which will, of course, be spaced apart a suitable distance to preclude a contact between the lamps which are to be supported therein, regardless of the severity of the vibration which the box will have to undergo incident to its conveyance upon an automobile. Moreover, the interior dimensions of the box should be presumed adequate to inclose five of the particular size and design of lamp which the box is purposed to contain. The resilient plates 6 and are mainly secured near or at the edges of one of them so as to establish an area, over all less than that defined by such edges, over the spread of which the plates are free with respect to each other. In this way a mutually reactive pair of juxtapositioned areas, or a series, as in this instance five divisional areas, are obtained, in consequence of the resilience of each of the plates.

The upper plate 7 is bent downwardly below the under plate 6 at each side and then again laterally to form flanges 8 to be secured in any approved manner to the bottom 5 of the box. These flanges are clearly seen in Figs. I and II. The plates 6 and 7 are provided with five main circular or re is tering openings 9 and 10 respectively. e openings 9 are provided with two pairs of diametrically opposite recesses 11.1 which extend from the edges of the openings. respectively. Each of the openings '10 is provided with a pair of diametrically opposite notches 12 corresponding in size and spaced relation to that of the pairs of recesses 11, and located directly opposite one pair of the recesses and at an angle of 90 from the other pair of recesses. The notches 12 open through the edges of the opening 10 and each notch" has its own bordering edges slightly raised in a direction away from the under plate 6. j I j Five 13 having bases 14 provided with oppositely disposed lateral projections 15 are adapted to have their bases supported in the registering openings 9 and 10, When so presenting them that the projections 15, which are equally spaced and proportioned as the notches 12, are in line. Thereafter, in response to the application of downward pressure the reactive areas offthe plates 6 and 7 may be sprung apart sufficient to permit the projections 15 to be turned into position between the plates until the spring action presently presses them into that pair of recesses which are at an angle of 90 from the notches, whereupon the lamps are firmly held in place until such time'when' the manipula-tion including the application of a turning force is repeated preparatory to the withdrawal of a particular lamp for use. The raising of the edges of the notches facilitates both the entrance to and final withdrawal from between the proximate space intervening between the plates and between the recesses as will be readily perceived.

I claim:

1. A lamp socket contrivance comprising inco-mbination with a lamp having a pair of lateral projections, of a pair of members adapted to afford a yielding relative action which is mutually inherent, one of said members being provided with an opening including notches,'the other of saidmember's having similarl spaced but differently locat'ed recesses adapted to be occupied by said projections; V

2. A device of the character described comprising a pair of fiat members superimposed one upon the other and so secured together as to enable limited relative separat ing movement, said members being provided withregistering openings, the edge of one member bordering its opening being provided with notches. w

3. A device of the character described comprising a box and a pair of fiat members superimposed one upon the other and together spaced from onewall of said box, said members being so seoured together as to enable limited relative separating movement, said members being provided with registering openings, the edge of one member bordering its opening being provided carried by such elevated area of the first in i such a way that a relative movement therebetween is permitted, and a socket formed about the edges of registering openings in said members.

5; A device or the "character aeseribed' comprising a box, a resilient member including an intermediate U-sh'aped portion and lateral flang s resting upon the bottom of said box whereby a certain flat area of said member is spaced from said bottom, another resilient and flat membercarriedby and in juxtaposition to such flat area of the first in such -a way that a separating movement tlierebetween is permitted, and a socket formed about the edges of registering openings in said members. 7

6. A lamp socketc'ontrivance for theaccommodation of a lamp base having lateral projections, comprising a pair of plates attached to each other at points surrounding a given area, one of said platesbeingresilr ent, one of said plates being provided with an opening located between said 'oints of attachment and having an edg fashioned with notches arranged and of a size like the projections on said lamp base, said projections exceeding the normal distance between said plates at sai'dopening, whereby arelative spreading action occurs between the plates when the base of the lamp is forcibly inserted and the projections thereon are caused to press against that plate which is beyond with reference to the directionof insertion movement, suchspreading action being maintained by turning the projections to a position betw en said Plates.

, 7. A lamp socket contrivance comprising the combination with a lamp basehaving a pair of lateral projections, of a pair of abutting plates, one of said plates being resilient, one of said plates being provided with openings fashioned with notches formed in the edges thereof, an, edge portion of said notches being bent in a direction away from the other plate to facilitate insertion orwithdrawal of the lamp projections. M

8. A box adapted to contain in firm spaced relation a plurality incandescent lamps having bases provided with lateral projections, said box provided interior-1y with a pair of abutting plates,one of said plates being resilient, said plates being so attached to each other as to leave a plurality of relatively movable juxtapositioned areas opposed in pairs, said areas of one of said plates surrounding openings fashioned therein, said openings being provided each with spaced notches opening through the boring edge thereof, said areas of the other plate being provided withtwo sets of recesses, each set being correspondingly spaced as and one set directly opposite said notches respectively, whereby the projections of aplurality of lamp bases may be caused to 00- 10 RALPH R.
